    For 170gr. and under, I stick w/ RL22.
    For 180, up to 190, IMR7828 seems to work well.
    150gr. MK
    210M primers, start about 2 gr. below 75gr.

    170gr. MK
    210M primers
    Win brass
    Always start lower, but these are really good loads, for a very fickle Sako 75 300WM.

    That 150gr. MK, is simply lethal in my rifle, w/ RL22.

    Hope this helps...sakofan.. [​IMG]

    For the 190 MK H1000 is hard to beat.

    My WinM70 in 300WinMag likes the 190SMK with 76grs of H1000 lit by a WLRM primer or 77grs with the F215. Shoots sub moa to 600yds, haven't shot it any farther. Velocity is around 2975fps with 25.5" barrel.

    I will ditto S1's suggestion of H-1000 as a best powder for the .300 Win. and also suggest H-4350. I burn a lot less H-4350 (10 grains) in my .300 with super results.
